Could you please point me to some log file or give me some hint where / why bw-noicon is crashing tirex?
Unfortunately not. Unlike the other styles I disabled that threw errors on startup, the bw-noicon didn't show any obvious errors.
The problem was that the mapnik backend died frequently and if all backends died, tirex-backend-manager appears to go into a livelock. The logs showed that the last tile processed was a bw-noicon and after I disabled it, the issue went away.
I have re-enabled bw-noicon now though at we'll see if the problem reappears or if it was caused by something else and just coincidence.
Since it is
automatically derived from the original osm-mapnik style I am a bit reluctant to introduce any manual changes, but if it helps speeding up rendering, I'm trying.
For low zoom rendering, it would be good if you can try and use the "no buildings index" on the planet_polygon table. I will try and make those changes on default style as well, so perhaps you can rederive it from there then?

However I could need some more hints about where the real trouble occurs with the style.
Cheers, Kay
